Table 147. TAP_DUR register description

DUR_[3:0]

Duration of maximum time gap for double tap recognition. Default: 0000

When double-tap recognition is enabled, this register expresses the maximum time between two consecutive

detected taps to determine a double-tap event. The default value of these bits is 0000b which corresponds to

16/ODR_XL time. If the DUR_[3:0] bits are set to a different value, 1LSB corresponds to 32/ODR_XL time.

QUIET_[1:0]

Expected quiet time after a tap detection. Default value: 00

Quiet time is the time after the first detected tap in which there must not be any overthreshold event. The

default value of these bits is 00b which corresponds to 2/ODR_XL time. If the QUIET_[1:0] bits are set to a

different value, 1LSB corresponds to 4/ODR_XL time.

SHOCK_[1:0]

Maximum duration of overthreshold event. Default value: 00

Maximum duration is the maximum time of an overthreshold signal detection to be recognized as a tap event.

The default value of these bits is 00b which corresponds to 4/ODR_XL time. If the SHOCK_[1:0] bits are set to

a different value, 1LSB corresponds to 8/ODR_XL time.
